SALMON-SLIMING MACHINE.

Specification of Letters Patent.

Patented Sept. 1, 1914.

Application filed January 31, 1914. Serial No. 815,704.

To all whom it may concern:

Be it known that 1, CHARLES T. CARSON, a citizen of the United States of America, residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Salmon-Sliming machines, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to fish cleaning machines, and has especially for its object the production of an eflicient salmon sliniing machine which will eificiently clean the salmon without the necessity of employing a number of workmen to handle the same. I Another object of the invention is the production'of a simple and eificient means for feeding the fish along the body of the cleaning or sliming machine so as to cause the fish to be readily cleaned.

With these and other objects in view this invention consists of certain novel combinations, constructions, and arrangements of parts as will be hereinafter fully described and claimed.

In the accompanying drawings :Figure 1 is a top plan view of the machine. Fig. 2 is a central longitudinal section through the machine. Fig. 3 is a transverse section through the machine taken on line 3-3, of Fig. 2. Fig. 4 is an end view of the discharge end of the machine. Fig. 5 is a side elevation of the machine. Fig. 6 is a detail perspective view of the hinge portion of the hood of the machine. Fig. 7 is a section taken on line 77, of Fig. 2. Fig. 8 is a transverse sectional view through one of the sections of the clamping hood illustrated in Fig. 6. Fig. 9 is a side elevation of one of the cleaning wheels. Fig. 10 is a vertical section through one of the cleaning wheels illustrated in Fig. 9. Fig. 11 is a section taken on line mm of Fig. 1.

By referring to the drawings it will be seen that 1 designates the frame which is supported upon the usual legs 2, and this frame 1 supports a substantially inverted ,V-shape top 3 which is provided with laterally extending sides 4 and a sheet metal hood 5 is placed over the top 3 as indicated clearly in Figs. 2 and 3. It will be seen that this hood 5 will constitute means for ing between the top 3 and the hood 5 by means of thetension springs 6 which are mounted upon the bolts 7 and these springs 6 engage the upper faces of the side portions 8 of the hood 5, thereby keeping. a tension upon the hood 5 but yet allowing suflicient movement to permit the passing of different size fish through the machine.

A plurality of bearings 9 are formed integral upon the framel and detachable sections 10 of these bearings are secured to the bearing portions 9 for firmly holding the transverse shafts llupon the frame 1 of the machine. A plurality of these shafts 11 are employed preferably five in number, and

upon the first shaft and intermediate its ends is keyed a feeding wheel 12 which feeding wheel is spurs 13, whic are preferably six in number arranged at equal distances apart to grip the fish and force the same forwardly to be cleaned by the cleaning rollers to be rovided with a plurality of hereinafter described. The top 3 is provided with apertures 14 throughout its length to permit the feeding wheels 12 to pass therethrough and the cleaning wheels 15 to pass therethrough to operate upon the fish passing through the machine. The spurs 13 are, of course, of sufficient length to grip the fish and force the same longitudinally of the machine. The hood 5 may be formed of any design desired and is preferably provided adjacent each cleaning wheel with a plurality of apertures 16 over which apertures fits a feeding nozzle 17 carried by. a feeding pipe 18 to facilitate the.

feeding of water to the fish to not only clean the fish but also to keep the machine free from accumulative matter.

The hood 5 near the entrance end of the machine is cut away as is illustrated at 19 Fig. 2 to allow the fish to be easily placed upon the machine. In placing the fish upon the machine the fish are split longitudinally and placed down upon the top 3 having the back of the fish extending upwardly and causing the fish to lie fiat in a substantially inverted V-shape position upon the top 3 and extend longitudinally of the machine. The fish is then moved forwardly and the spurs 13 of the feeding wheels 12 engage the backbone of the fish and force the same into engagement with the first cleaning roller 15. The water passing upon the fish and also the cleaning wheel 15 will cleanse the fish to some extent and since the cleaning roller 15. v

will rotate the under portion of the fish will be somewhat cleaned as the fish passes longitudinally of the machine. The first shaft which supports the first feeding wheel. 12 carries a large sprocket wheel 20 over which passes a sprocketchain 21, and this sprocket chain in turn passes over a smaller sprocket wheel 23 carried by the shaft which supports the first cleaning roller or brush. The gears 20 and 23 are so arranged as to cause the brush 15 to be driven at twice the rate of speed of the wheel 12, thereby facilitating the cleaning of the fish. The opposite end of the shaft which supports the gear wheel 23 carries a small sprocket wheel similar to "the sprocket wheel 23 and over this sprocket scribed, and as stated above a water feed or I supply may be arranged above each of the cleaning wheels.

For the purpose of thoroughly cleaning the entire inner face or inner portion of the fish a plurality of cleaning belts 26 are em ployed, which belts pass over a driving drum 27 and an idler drum 28. These belts 26 are of an endless belt-type, and are provided with a plurality of rubber knobs or projections which are preferably of one-eighth di; ameter and one-fourthin height to produce an efficient roughened surface to act upon the inner face of the fish. The belts 26 pass through the transversely extending apertures 29 sufficiently to engage the inner face of the fish, and by continually rotating the belt 26 it will be seen that the fish will be efficiently cleaned. The driving drum 27 is driven by means of a beveled gear 30 which beveled gear meshes with a gear 31 carried by the central feeding wheel supporting shaft. Both the idler drum 28 and driving drum 27 are mounted upon suitable supporting brackets suspended from the under face of the top 3. Thisstructure is clearly illustrated in Fig. 11.

The last feeding wheel supporting shaft, or in other words the shaft which is at the discharge end of the machine carries a driving sprocket 32 over which a driving sprocket chain 33 passes, and this chain also passes over a sprocket wheel 34 driven by the power shaft 35. The power may be imparted to the shaft 35 by any suitable means passing over the wheel 36.

The hood 5 is provided near the delivery or discharge end of the machine with an aperture 37 and within this aperture 37 is mounted a hinge back clamp 38. This back clamp 38 carries a hinge 39 which is hing- .of sections which are connected to the hinge 39 to allow the free movement of these sections independently. The sections of the back clamp 38 are provided with an inner lining 41 which comprises a plurality of projecting portions 42 adapted to be clamped upon or held in engagement with the back of the fish for removing the scales therefrom as the fish are drawn under the sections of the "back clamp 38 by means of the last feeding wheel 12 illustrated clearly in Fig. 2.

Brackets 43 are carried by the hood 5 and :straddle the respective sections of the back clamp 38 andare provided with a plurality of apertures, through which apertures extend the bolt portions 44 of the back-clamp 38. These bolt portions 44 carr Y coil springs 45 which normally exert a downward pressure upon the back clamp 38, and nuts 46 are threaded upon the outer ends of the bolts 44' so as to limit the inward swing of the back clamp 38 upon the top 3. i

The cleaning wheels 15 are provided with laterally extending collar portions 47 which are adapted to fit snugly upon the shafts adapted to support the same and a rubber coverin 48 is mounted upon the cleaning wheels l5 and comprises a plurality of pro- ]ect1ng knobs simllar in construction to those referred to in connection with the back clamp illustrated clearly in Fig. 6.

By referring to Fig. 8 it will be seen that the inner lining 41 of the back clamp comprises a rubber sheet having the knobs 42 formed thereon, and this sheet is held in engagement with the body of the back by means of substantially T-shape rubber knobs 49.

Havingthus described'the invention what prising a frame, a substantially inverted V shape top provided with a plurality of alined apertures, feeding wheels extending through some of said apertures, cleaning wheels extending through other of said apertures, a shield hood positioned over said top, means for yieldably supporting said shield hood upon said top, and means for feeding water to said hood.
